"I have not spoken to or seen Nicole in quite some time and that's not through lack of trying," she told The Mirror.

"I've made enough first moves now, I feel the ball is in her court."

She continued: "I just hope that Nicole is actually happy as a person. Our dealings together weren't always easy - it wasn't an easy situation to be in, in the Pussycat Dolls, period.

"But I have a lot of love for Nicole and if she offered [an olive branch] I would accept it with open arms. I have a lot of understanding but, at the same time, I wish we could get past that and just move on."
